Cl. 248-97 6 Claims ABSTRACT OF THE DISCLOSURE BACKGROUND OF THE INVENTION There has been a recent trend in metropolitan areas and institutional organizations, such as restaurants, hospitals and the like, to do away with permanent waste or garbage containers and cans by substituting large (40" or more in height) garbage bags or containers which can be handled without contamination and which would easily permit disposal of garbage and trash. Each container or bag generally holds 30, 40 or even 50 pounds of refuse. Various attempts have been made at producing inexpensive and eflicient frames, and holders to support such refuse bags or containers during the filling thereof. A great majority of these devices embody the concept of an interior metal ring or collar over which is slipped the top margin of the container thereupon securing the container to the supporting apparatus. The basic disability of this prior art concept is the exposure of the metal collar or ring to contamination and the relative difliculty of securing the bag in place.

Therefore, an object of this invention is to provide in combination, a waste container and holder therefore, which will minimize the inherent unsanitary conditions of the typical prior art units.

Also, various attempts have previously been made at supplying a waste disposal container adapted to cooperate with a holder having parallel horizontal supporting arms. Among these have been the provision of supporting arm receiving tubes secured to the upper sides of the container. The receiving tubes are fabricated separately from the container and are subsequently secured thereto. This obviously provides greater manufacturing costs due to the provision and handling of additional components.

Accordingly, it is a further object of this invention to provide an inexpensive waste disposal container for cooperation with a holder having parallel horizontal arms which will minimize necessary materials for the container fabrication.

Another attempt at providing supporting arm receiving slots involved the provision of vertical slits at the upper corners of a bag, folding the resulting side flaps downwardly and securing them to the outer sides of the bag. This, of course, results in manufacturing difiiculties due to the many and complex manipulations required of automatic container manufacturing equipment.

Therefore, it is another object of this invention to provide a waste container for cooperation with a holder having parallel hrizontal arms which will simplify manufacturing processes and lend itself to manufacture by conventional container-fabricating equipment.

3,491,973 Patented Jan. 27, 1970 A further object of this invention is to provide in combination a waste container and holder therefore, which cooperate to minimize the inherent difliculty of attaching and detaching waste containers from the supporting structure of prior art.

An additional object of this invention is to provide an easily replaceable and inexpensive waste container.

Another object of this invention is the provision on inexpensive waste containers of means whereby the containers may easily and rapidly be attached to and detached from a cooperating holder.

A further object of this invention is to provide an inexpensive holder for supporting replaceable waste containers such that the replacement of the container may be carried out rapidly and efliciently by unskilled personnel.

SUMMARY The applicant has solved the above mentioned problems by providing a waste container holder having parallel horizontal arms and a cooperating multi-ply waste container. The container comprises slits in its outer ply such that the arms of the cooperating holder may extend between the plies of the container to provide support for the container and maintain it in a top-opened condition and ready to receive refuse.

The inner and outer plies of the container are welded together along the upper sides of the container such that the welded portion of the container rests upon the horizontal arms of the holder.

The arms of the holder, being between the plies of the container, are not exposel to waste and refuse deposited in the container, thus preventing an unsanitary condition through simple and inexpensive means.

Additionally, the cooperating holder and container enable a simple exchange of a full container for an empty one. The user merely slips the full container off the holder and an empty one on without resorting to collars and clamps for purposes of holding the container in place.

As a further boon to expediency, the applicant has provided a holder having a rack for holding extra empty containers. This eliminates the problem of the user going to a storage closet each time he needs an empty container and results in much time and effort saved.

These and other advantages of this invention will become apparent when taken together with the accompanying drawings.

DETAILED DESCRIPTION Referring now to FIGURES l-8, the container of this invention is shown in conjunction with one embodiment of the cooperating holder. Referring particlarly to FIG- URE 1, the holder designated generally by reference numeral 10 is comprised of base 11 and vertical standard 12 which extends upwardly from base 11 and is secured thereto by any appropriate fitting such as flange connection 13. U-shaped bag supporting member 14 is fastened to vertical standard 12 and spaced from the base 11 by a distance sufiicient to provide room enough for the insertion of a waste container which will hold upwards of 50 pounds of refuse. The arms of the U-shaped bag supporting number 14 are designated by reference numeral 28 (see FIGURE 2) and are maintained in a horizonal plane and in parallel relation to each other. Referring now to FIGURE 3, the U-shaped bag supporting member 14 is secured to the vertical standard 12 through fastening means comprising semi-tubular fitting 15, extending around vertical standard 12 and secured to plate 16 in any conventional manner such as by bolts 17. It will be noted that tubular-shaped fitting 15 and plate 16 provide a friction coupling with vertical standard 12. Cantilever support member 18 is fastened to the upper portion of plate 16 also in a conventional manner such as by bolts 19 (see FIGURE 4). The lower end of support plate 20 (FIGURES 3 and is fastened to the free end of cantilever support member 18 by bolts 21. U-shaped bag supporting member 14 is then secured to the upper portion of support plate 20 by bolts 22.

The supporting apparatus or holder has been depicted as comprising various members secured together in a conventional manner. It is also conceived that the holder may be fabricated from appropriate materials such that the various members are integrally connected.

It will be noted from FIGURE 5 that cantilever support member 18 and U-shaped bag supporting member 14 are of such configuration as to provide a horizontal spacing 29 therebetween when assembled as previously mentioned. This space is provided to enable the outer ply of the waste container to be positioned therebetween when a container is mounted on the holder as will be hereinafter explained.

The supporting structure or holder may comprise a rectractable cover such as that designated by reference numeral 23 in FIGURES l and 3, the cover being pivotally mounted on holder at 24. The cover may be provided with a coil spring 25 to aid in the lifting thereof. The spring 25 as depicted is connected to holder 10 aat 27 and to the cover 23 at 26. Referring now to FIGURE 1, cover 23 may be provided with rests 30 attached to its inner surface by appropriate fasteners such as rivets or the like. Cover rests 30 press firmly against the upper edge of each parallel bag supporting arm 28 when the cover is closed, thus securing the bag therebetween and preventing the bag from being inadvertently knocked off the support.

Referring now to FIGURE 6, the preferred embodiment of the waste container of this invention is in the nature of a paper bag and is designated generally by reference numeral 50. The bag is of multi-ply construction and comprises inner ply 51 and outer ply 52. The plies are laminated, as at 53 in FIGURE 7, in a band extending from and parallel to the upper periphery of the bag 50 along each side thereof. The laminated portion of the plies is shown as a band in the drawings however, it is also conceived that the lamination may be provided by a series of spot welds adjacent the upper periphery of the bag. The outer ply 52 of the 'bag is provided with slits 54 in side walls relatively near an end wall of the bag. The upper extremity of the slit 60 (see FIGURE 6) terminates at the lower edge 61 of the laminated portion 53. An

unlaminated portion 55, shown in FIGURE 8, is thus provided which extends inwardly from slits 54 between plies 51 and 52, and parallel to the laminated portion 52, and of a width at least equal to the length of slits 54 thus providing internal support receiving pockets.

Therefore, the unlaminated support receiving pockets 55 of the bag 50 are adapted to receive the container supporting arms 28 of holder 10 through slits 54. It will be seen that the outer ply 52 of the bag adjacent the unlaminated portion 55, slips into space 29 between U- shaped member 14 and cantilever support member 18, as best shown in FIGURE 5. It can readily be seen that arms 28 of the bag supporting member 14 are substantially covered by the bag material; therefore, waste or debris deposited in the container will not catch or build up on the extended arms, thus resulting in a more healthful environment in the area of the container.

With regard to the laminated portion of the bag, the only limiting factor is that the plies must be laminated along the sides of the bag extending from the upper periphery thereof, downwardly to the upper extremity 60 of slits 54. For a 50-pound refuse bag, a laminated band width of approximately 2 inches has been found suflicient, the band width becoming progressively narrower for bags intended for lighter loads. For a 30-pound bag, a laminated band width of has been found suflicient. With the exception of the unlaminated portion 55, the laminated area may extend to all or any other part of the bag.

The upper laminated band may thus be folded downwardly, over the U-shaped bag supporting member 14 such that it will not impede the placing of refuse in the bag, and in addition will completely encompass the U- shaped bag supporting member, protecting it from contact with refuse, therefore preventing a build-up of refuse on the bag-supporting member and perpetrating a more healthful environment.

Thus it can be seen this invention provides a cooperating bag and holder which may be inexpensively and simply manufactured and which will aid in waste disposal in a highly sanitary manner.

FIGURE 2 depicts an alternative embodiment of the container whereby additional slit 56 is provided parallel to slit 54 in each side of the outer ply 52 of the bag 50 and relatively near the other end thereof. Therefore, the arms 28 of the holder 10 may extend through the additional slit 56 such that the holder may accommodate bags of various sizes while maintaining the weight of the container and refuse therein near the base of U-shaped member 14.

FIGURES 9-12 show an alternative embodiment of the cooperating waste container holder designated generally by the reference numeral (see FIGURE 9). The holder 70 is comprised of bag supporting arms 71 which include an upper bag supporting surface 72 and a lower support strut 73. The bag supporting portion 72 of bag supporting arms 71 is secured to telescoping vertical support member 74 at 75 by any appropriate means, such as a weld, and the lower support strut 73 is secured to telescoping vertical support member 74 at 76 by appropriate fasteners such as machine screws.

In this embodiment, the bag supporting arms 71 have been depicted as being fabricated from one continuous length of material such as aluminum tubing or the like. The tubing is bent to the appropriate configuration, i.e. to include each bag supporting arm 71 in addition to handle portion 77. Handhold 78 provided therefor may be fabricated from plastic or the like.

The bag supporting arms are maintained in a bag supporting position by the cooperation of telescoping vertical support member 74 and tubular uprights 79. The inside diameter of tubular upright 79 closely approximates the outer dimension of vertical support member 74 such that a relatively friction-free slidable fit is achieved between vertical support member 74 and tubular upright 79.

The height of bag supporting surface 72 may be adjusted by means of the vertical series of tapped holes 80' in tubular upright 79. Adjusting pins 81 upon which the bottom of vertical support member 74 rests may be selectively positioned in the series of holes 80 to vary the height of the bag supporting surface.

Tubular uprights 79 are maintained in a vertical position by means of brace portion 82 of the combination support member extra bag holder 83 which is secured to tubular upright 79 at 84 and to U-shaped base member 85 at 86. The connections at 84 and 86 may be made by any appropriate fastener such as machine screws. U- shaped base supporting member 85 is secured to the lower portion of tubular uprights 79 by means of L-shaped brackets 87 on each side of the connection. Each pair of L-shaped brackets 87 is secured to an end of the U-shaped base member 85 by means of any appropriate fastener such as a machine screw 88 passing through one L-shaped bracket, the end of U-shaped base member 85, and finally through the second L-shaped bracket member whereupon it is then secured in position by any appropriate means such as a nut and lock washer. L-shaped brackets 87 are then secured to the lower portion of tubular uprights 79 by means of axle 89 passing through the inner L shaped bracket, the lower portion of tubular upright 79, the outer L-shaped bracket, and finally through wheels 90 which provide the unit with an element of mobility.

U-shaped base member 85 has been provided with a plurality of struts 91 for support purposes. Each strut 91 may be secured to each leg of the U-shaped base member in any appropriate manner such as by welding. Extra bag holder portion 92 of the combination support memberbag holder 83 extends upwardly from the connection 84 with tubular uprights 79. Referring now to FIGURE 12, it will be seen that extra bags 93 may be held in position between extra bag holding member 92 and tubular upright 79. Thus, when a bag 50' is filled with refuse, it may be removed and replaced with an extra bag in a minimum of time and efiort on the part of the operating personnel.

Referring now to FIGURE 10, it will be seen that the holder of this embodiment is of a collapsable nature. When it is desired to collapse the holder, the upper portion comprised of the support arms and vertical support member 74 may be raised upwardly thus removing vertical support members 74 from the tubular uprights 79. Fasteners at 86 are removed thus freeing brace member 82 from U-shaped base member 85. At this point combination support memberextra bag holder 83 may be pivoted about fastener 84 to the position shown in FIGURE 10. Also, U-shaped base member 85 may be pivoted about fastener 88 to the position shown in FIG- URE 10. The unit may then be stored away in a relatively small space.

It is conceived that each major element of the holder of this embodiment may be fabricated of aluminum tubing. This will provide a very light but rigid holder which may be moved from place to place with relative ease.

Referring now to FIGURES 11 and 12, it will be seen that bag supporting arms 71 extend through slit 54 in the outer ply of the bag 50 and into the unlaminated area 55 between inner and outer plies of the multi-wall waste container. Thus the bag supporting arms are covered over a major part of its surface such that no waste or debris can come into contact therewith to cause an unsanitary condition.

From the foregoing description and reference to the accompanying drawing it will be seen that I have provided an inexpensive and rapidly replaceable container which will perpetuate a sanitary condition in the area of the container.

It will be understood that various changes and the details, materials, steps and arrangement of parts which have been herein described and illustrated in order to explain the nature of the invention, may be made by those skilled in the art within the principle and scope of the invention as expressed in the appended claims.
